I am trying to run a simple program which does Sendrecv between two nodes
having 2 interface cards on each of two nodes.
Both the nodes are running RHEL6, with open-mpi 1.4.4 on a 8 core Xeon
processor.
What I noticed was that when using two o

Hello Everyone,
This is my 1st post in open-mpi forum.

more than one interface
I had exactly the same problem.
Trying to run mpi between 2 separate machines, with each machine having
2 ethernet ports, causes really weird behaviour on the most basic code.
I had to disable one of the ethernet ports on each of the

Yes, they were on the same subnet. I guess that is the problem.

Unfortunately, there isn't a lot of good
